Details:
Steps:
0. insmod several video modules.
1. Run videoinfo.
2. rmmod a random video module.
3. Run videoinfo again. Observe that the video adapter did not disappear from
the list.
Doing this a few times may even trick GRUB into running an infinite loop.
In include/grub/video.h, routine grub_video_register should initialise
adapter->prev to p. Otherwise grub_list_remove is unable to remove all
references to the grub_video_adapter_t structure.
